Can anyone tell me or point me to a place that specifies what the minimum distance between drilled holds in a joist/beam is when running cables down a wall from the roof without affecting the structural integrity of the joist/beam?

Similarily how big can the hole be compared to the width of the beam/joist?

The plan is to run a few cat6 + coax cables down the wall (each outlet will have about 4xcat6 + 2xRG6 cables.

Appreciate any help.
